StumbleUpon announced today that its 5by video discovery service has partnered with VICE Media, Tribeca Enterprises, and DEFY Media. These are its first-ever media partnerships.

As a result of these partnerships, users will be able to navigate partner channels to watch “freshly curated” video playlists. Partner experiences will appear on the home screen or as channels, depending on time of day and individual preferences.

With the partnership news, the company also announced that the iOS app, like the Android app, now supports Google’s Chromecast as a living room viewing option.

“We’re ecstatic to launch these new channels and introduce great content and brands to our growing audience. Innovation is in 5by’s DNA and we’re thrilled to grow with VICE, Tribeca, and DEFY,” said 5by CEO Greg Isenberg. “These partnerships represent a growing interest in 5by advertising across different categories, but our focus remains on building a great product.”

“We’re excited to add some of our original video content from the ScreenJunkies, AWEme, Break, and SmoshGames properties on 5by,” added Barry Blumberg, EVP Content and Programming, Defy Media. “We’re committed to distributing our award-winning content across emerging platforms, including mobile, and this provides another avenue our viewers can use to discover and consume our videos when and where they want.”

StumbleUpon acquired 5by last fall, and launched the apps for iOS and Android in January. Read our interview with Isenberg here and our interview with StumbleUpon CEO Mark Bartels here.

Isenberg told us that the plan was to continue to expand to new platforms, and “really take over the living room. TV apps, gaming consoles, you name it.”

Bartels similarly discussed interactive TVs and gaming consoles.
